A now available second maintenance release for PHP 5.3 fixes more than 60 bugs and closes several security holes which were already corrected in version 5.2.13, from the 5.2 branch, last week.

Among the problems is a validation flaw in the safe_mode configuration variable within the tempnam() function that occurred when the directory path didn't end in "/)". The developers also fixed an open_basedir/safe_mode bypass vulnerability in the session extension.
